摘要：

Variational envelope function of an exciton in a single quantum well wire (SQWW) is described in the framework of the effective mass approximation for two-band model. The SQWW considered has thickness values : L(z) < a(B), along the growth axis of the sample, and L(x) > 3a(B) for the lateral dimension (where a(B) is the Bohr radius). Exciton polarizations and optical response for SQWW and for a grating of QWWs are given. The role of the local fields on the optical response of these two different superstructures is pointed out.
